Description

Technical Field

[0001] The present application relates to the technical field of automobile parts, and in particular to a flush frame door assembly and an installation method thereof. Background Art

[0002] The flush door structure is an innovation in the field of automobile design in recent years, which aims to improve the appearance and aerodynamic performance of the car. The traditional door structure usually has a step difference between the window glass and the door frame. This design not only affects the appearance of the whole vehicle, but also may cause greater wind resistance and noise when driving at high speed, thus affecting the riding experience.

[0003] As consumers' requirements for automobile appearance and performance increase, the flush door structure came into being. This structure optimizes the connection between the window glass and the door frame so that the outer side of the window glass and the outer side of the door frame are on the same plane, thus eliminating the step difference in the traditional design. This design not only improves the visual effect of the entire vehicle, but also effectively reduces the wind resistance coefficient, improving the vehicle's fuel economy and driving stability.

[0004] Related prior arts such as the Chinese patent application “A novel flush door structure”, application number 202221333320.5, discloses a door glass, a window frame outer decorative panel and a window frame inner panel located on the inner side of the window frame outer decorative panel, a door window frame reinforcement plate is provided between the window frame outer decorative panel and the window frame inner panel, a guide groove sealing strip is provided between the door window frame reinforcement plate and the door glass and the window frame outer decorative panel, a window frame guide groove is formed on the guide groove sealing strip, a slider is fixed to the inner side of the door glass near the window frame outer decorative panel, one end of the slider can be slidably adapted in the window frame guide groove, and the outer side surface of the connection part between the door glass and the window frame outer decorative panel is on the same plane.

[0005] The existing door trim panel structure is an integrated structure, which causes certain inconveniences when installing the sealing strip and the glass slider. In addition, the installation limit of the glass slider is basically only realized by the sealing strip, and the sealing strip is easily deformed by force, so the installation stability of the glass slider is not high. Summary of the invention

[0006] The technical problem to be solved by the present application is to provide a flush frame door assembly and an installation method thereof, which splits the decorative panel into two parts, facilitates the installation of the sealing strip and the glass slider, and ensures that the structure is stable and reliable after the decorative panel is installed.

[0007] The technical solution adopted in this application is: a flush frame door assembly, including sheet metal parts, decorative panels, sealing strips and glass sliders, The decorative panel includes a base strip and a baffle strip, one end of the base strip is a U-shaped structure placed horizontally, which is recorded as a U-shaped member, the U-shaped member includes a horizontal plate located at the bottom, and a bayonet is arranged on the horizontal plate, the baffle strip includes a bottom plate and a baffle plate, the baffle plate is vertically arranged on the bottom plate to form an L-shaped structure, and a buckle is arranged on the bottom plate to protrude downward; The sealing strip includes a U-shaped groove, which includes a short strip, a bottom strip and a long strip connected in sequence. The long strip is provided with a first depression and a second depression. The first depression is arranged closer to the bottom strip than the second depression. The first depression is located above the long strip, and the second depression is located below the long strip.

[0008] Compared with the prior art, the advantage of the present application is that the traditional integrated door decorative panel is divided into a base strip and a stop strip, so when assembling the car door, the base strip can be pre-installed, and then the sealing strip, glass slider and other structures are assembled, and then the stop strip is inserted, and the base strip and the stop strip are installed by clamping the bottom plate and the cross plate. The present application adopts a split decorative panel structure, which is convenient for the installation of the sealing strip and the glass slider, improves the production efficiency of the car door, and makes the later maintenance and replacement more convenient.

[0009] In this application, for the convenience of description, the Figure 3 The relative positions of the components are described as a benchmark and do not imply the actual status of the product itself during use.

[0010] In some embodiments of the present application, the base strip includes a top plate, a vertical plate and a horizontal plate, the vertical plate is connected to the bottom of one end of the top plate, the horizontal plate is connected to the bottom of the vertical plate, and one end of the top plate, the vertical plate and the horizontal plate constitute the U-shaped member; two relatively arranged clip strips are arranged on the periphery of the bayonet, the clip strips are in an L-shaped structure erected on the horizontal plate, the two clip strips are in an inverted U-shaped structure, and the bayonet is located within the distance between the two clip strips.

[0011] The outer periphery of the buckle is provided with a U-shaped notch, which makes the buckle structure have better elastic deformation performance, and cooperates with the bayonet to realize the connection between the baffle bar and the base bar. The slidable baffle bar structure is compact and has a deformable fastening structure, and can prevent the baffle bar from moving after fastening.

[0012] The U-shaped design makes it easier to position and fix the sealing strip and glass slider during installation, which simplifies the assembly steps and improves production efficiency. The two L-shaped clips set around the bayonet form an inverted U-shaped structure. This design can effectively limit the relative displacement between the base strip and the stopper, ensuring the firmness and reliability of the connection during use. The split design makes it more convenient for later maintenance and replacement. Users can replace damaged parts separately without replacing the entire assembly.

[0013] In some embodiments of the present application, the card strip includes a vertical bar and a horizontal bar, the vertical bar is arranged perpendicular to the horizontal plate, and the horizontal bar is arranged parallel to the horizontal plate, the baffle plate is provided with a first notch adapted to the horizontal bar, and the bottom plate is provided with a second notch adapted to the vertical bar, and the first notch is connected to the second notch; when the baffle bar is inserted into the base bar, the card strip passes through the first notch and is inserted into the second notch, and the vertical bar is fitted on top of the bottom plate.

[0014] The present application limits the relative displacement of the base bar and the stop bar in the length direction by inserting the card bar into the second notch. The vertical bar is attached to the top of the bottom plate, and a horizontal plate is arranged below the bottom plate, which limits the relative displacement of the base bar and the stop bar in the vertical direction.

[0015] The design of the vertical and horizontal bars forms a more stable clamping structure, which can effectively limit the relative displacement between the base bar and the baffle bar and enhance the stability of the connection. The design of the first notch and the second notch allows the baffle bar to pass smoothly when inserted into the base bar, which simplifies the installation steps, reduces the reliance on tools and improves assembly efficiency. The coordination between the baffle bar and the base bar is more precise and can adapt to different installation conditions, ensuring a good connection effect in all situations.

[0016] In some embodiments of the present application, the base plate has a stepped structure, and the base plate includes an upper plate and a lower plate, the upper plate is arranged higher than the lower plate, and the second notch is located in the upper plate; the outer side surface of the cross plate is an inclined guide surface, and the bending part of the base plate is in contact with the guide surface of the lower panel.

[0017] The stepped structure and inclined guide surface design of the bottom plate allow the stop bar to be inserted into the base bar more smoothly during installation, reducing the difficulty of alignment and improving assembly accuracy. The layered design of the upper and lower plates can effectively disperse the force, enhance the stability of the overall structure, and reduce deformation and damage during use.

[0018] In some embodiments of the present application, one end of the glass slider has a rectangular cross-section and is installed in the U-shaped groove of the sealing strip, and the other end of the glass slider extends from the U-shaped groove of the sealing strip and is supported under the vehicle window glass; the other end of the top plate has a hook structure for installing sheet metal parts.

[0019] The hook structure of the top plate provides an additional fixing point for installing sheet metal parts, enhancing the stability of the overall structure and ensuring that it will not loosen or fall off during use. The rectangular structure design at one end of the glass slider provides better support in the U-shaped groove of the sealing strip, ensuring the stability of the window glass during use and reducing shaking and noise.

[0020] In some embodiments of the present application, a first ridge is arranged on one side surface of the baffle plate close to the vertical plate, the first ridge is arranged along the length direction of the baffle plate, and the cross-section of the first ridge is a triangular structure; a second ridge is arranged on one side surface of the vertical plate or the bottom plate close to the first ridge, the second ridge is arranged along the length direction of the vertical plate, the cross-section of the second ridge is a triangular structure, and the second ridge is arranged higher than the first ridge.

[0021] The ridge design with a triangular cross section can effectively prevent the baffle from sliding when subjected to force, ensuring the safety and reliability of the component during use. The ridge setting can form a better sealing effect between the baffle and the sealing strip, reduce wind noise and water penetration, and improve the comfort and safety of the vehicle.

[0022] In some embodiments of the present application, a third ridge is arranged below one end of the top plate, the third ridge is arranged along the length direction of the top plate, the cross-section of the third ridge is a triangular structure, the third ridge is arranged opposite to the cross plate, and the first ridge, the second ridge and the third ridge act on the sealing strip.

[0023] In the present application, the sealing strip is also provided with corresponding recesses corresponding to the first convex ridge, the second convex ridge, and the third convex ridge, and is stably installed with the convex ridges. Such a design makes it easier to install and fix the sealing strip during the installation process, simplifies the installation steps, and improves the assembly efficiency.

[0024] A method for installing a flush frame door assembly includes the flush frame door assembly, and the installation method includes the following steps: 1) Fix the base strip to the sheet metal; 2) Install the U-shaped groove of the sealing strip into the U-shaped groove of the base strip; 3) Insert the glass slider into the U-shaped groove; 4) Fit the bottom plate of the baffle strip onto the horizontal plate and move it toward the U-shaped piece until the buckle is embedded into the bayonet and the baffle strip is snapped into the base strip. The baffle plate on the baffle strip acts on the long strip of the sealing strip to bend the long strip of the sealing strip into a horizontal L-shaped structure, wherein the first recess of the long strip is located at the bottom of the baffle plate, and the second recess of the long strip is located at the top of the baffle plate.

[0025] Compared with the prior art, the advantage of the present application is that the traditional integrated door trim is divided into a base strip and a baffle strip. When assembling a car door, the present application sets the base strip and the sheet metal part to be installed first, and the base strip is provided with a U-shaped part to realize the installation of the U-shaped groove of the sealing strip. Different from the prior art, the sealing strip structure of the present application can be designed with a relatively simple U-shaped structure, and the first recess and the second recess are correspondingly provided on the long strip constituting the U-shaped groove to cooperate with the subsequent installation deformation. Therefore, after the sealing strip of the present application is installed, the opening of the sealing strip is larger, which is convenient for the installation of the glass slider. Then, the bottom plate of the baffle strip is fitted on the horizontal plate and moved toward the U-shaped part until the buckle is embedded in the bayonet and the baffle strip is connected with the base strip. At this time, the installation of the flush frame door assembly is completed. And because the baffle on the baffle strip is arranged perpendicular to the bottom plate. After the baffle and the base strip are snapped into place, the baffle will apply force to the long strip of the sealing strip. With the arrangement of the first and second recesses on the long strip, the long strip of the sealing strip will naturally be deformed by force to form a horizontal L-shaped structure. In other words, the U-shaped groove opening of the sealing strip is closed after installation, and the glass slider is locked in the U-shaped groove. On the one hand, the present application facilitates the installation of the sealing strip and the glass slider, and improves the assembly efficiency of the flush frame door assembly. On the other hand, the installation method of the present application makes the installation of the glass slider and the sealing strip on the decorative panel more stable and reliable, and improves the quality of the product.

[0026] Specifically, the base strip of the decorative panel can be fixed with screws or the like, and the split baffle is designed to be L-shaped with a compact structure, which can reduce the lateral size of the decorative panel, thereby reducing the lateral size of the sheet metal and reducing the weight of the body sheet metal.

[0027] The above installation method allows for the removal of a part during later maintenance and replacement without disassembling the entire assembly, thereby improving the convenience of maintenance. In the above installation method, the design of the baffle can ensure the tight connection between the various components, enhance the stability of the overall structure, and reduce looseness and deformation during use.

[0028] In some embodiments of the present application, after the U-shaped groove of the sealing strip is installed in the U-shaped groove of the base strip, the long strip portion of the sealing strip is mounted on the clamping strip, and the long strip portion of the sealing strip is bent.

[0029] In the present application, by setting up a clamping strip structure, firstly, the baffle strip and the base strip can be firmly clamped together, and secondly, the clamping strip can make the sealing strip partially warp after installation, which is convenient for the subsequent insertion and installation of the baffle strip. When installing the glass slider, the long strip of the sealing strip can be straightened without too much obstruction, which is convenient for the glass slider to be installed into the sealing strip. At the same time, after the glass slider is installed, the clamping strip and the sealing strip can play a role in positioning the glass slider.

[0030] In some embodiments of the present application, after the baffle strip is connected to the base strip, the first recess of the strip is located at the connection between the baffle plate and the horizontal plate, and the second recess of the strip is located at the corner of the top surface of the baffle plate near the vertical plate. The design of the first recess and the second recess can effectively form a better sealing contact with the decorative plate, reduce wind noise and water penetration, and improve the sealing effect of the door assembly. The design of the recess enables the baffle strip to better adapt to different installation conditions when connected to the base strip, ensuring that a good connection effect can be achieved in various situations.

[0031] The above-mentioned implementation modes can be combined arbitrarily based on the common knowledge in the art. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The outer periphery of the buckle 24 is provided with a U-shaped notch, which makes the buckle 24 structure have good elastic deformation performance, and cooperates with the bayonet 10 to realize the clamping of the baffle 6 and the base bar 5. The slidable baffle 6 has a compact structure and a deformable fastening structure, and can prevent the baffle 6 from moving after being fastened.

[0042] The design of the U-shaped piece makes it easier to position and fix the sealing strip 3 and the glass slide 4 during installation, simplifies the assembly steps, and improves production efficiency. The two L-shaped clips 11 arranged around the bayonet 10 form an inverted U-shaped structure.

The design of the recess enables the stop bar 6 to better adapt to different installation conditions when connected to the base bar 5, ensuring that a good connection effect can be achieved in various situations.

[0063] The sealing strip 3 structure of the present application is provided with a first recess 13 and a second recess 14 on the strip 30 constituting the U-shaped groove, which are used to cooperate with the subsequent installation deformation. Therefore, after the sealing strip 3 of the present application is installed, the opening of the sealing strip 3 is larger, which is convenient for the installation of the glass slider 4. Then, the bottom plate 12 of the baffle 6 is fitted on the horizontal plate 7 and moved toward the U-shaped part until the buckle 24 is embedded in the bayonet 10 and the baffle 6 is engaged with the base strip 5. At this time, the installation of the flush frame door assembly is completed. Because the baffle 27 on the baffle 6 is arranged perpendicular to the bottom plate 12. After the baffle 6 and the base strip 5 are engaged in place, the baffle 27 will apply force to the strip 30 of the sealing strip 3. With the arrangement of the first recess 13 and the second recess 14 on the strip 30, the strip 30 of the sealing strip 3 will naturally be deformed by force to form a horizontal L-shaped structure. In other words, the opening of the U-shaped groove of the sealing strip 3 after installation is closed, and the glass slider 4 is locked in the U-shaped groove. On the one hand, the present application facilitates the installation of the sealing strip 3 and the glass slider 4, and improves the assembly efficiency of the flush frame door assembly. On the other hand, the installation method of the present application makes the installation of the glass slider 4 and the sealing strip 3 on the decorative panel 2 more stable and reliable, thereby improving the quality of the product.
